A British mother accused of smuggling heroin has spoken of her torment at having to bring up her baby daughter in a Pakistani prison cell.

Khadija Shah says nine-month-old Malaika is the only thing keeping her sane as she waits to find out if she will face the death penalty for her alleged crimes.

The 25-year-old from Birmingham has not had a date set for her trial, 14 months after she was arrested on suspicion of trying to smuggle £3.2million of heroin into the UK.

She gave birth to Malaika in October, but was then forced to return with her to the Rawalpindi Central Jail, where she fears the baby will be struck down with one of the infectious diseases such as tuberculosis which are rife in the prison.

Maya Foa of Reprieve said: 'We are extremely worried about Khadija and the health of her baby.

'What is still more troubling is that the British Government is complicit in her plight - by giving aid to Pakistan’s counter-narcotics programme, the UK is in effect helping to send people to death row for drugs offences, including its own citizens.'

The young mother has denied any wrongdoing ever since she was arrested at Islamabad Airport in May last year.

She claims she agreed to transport some suitcases as a favour for men she had recently met, and had no idea that the luggage contained heroin.
